Reads and writes files in the new JPEG 2000 image format.

This is just an inteface to the external program "jasper" that can code/decode JPEG 2000 images (.JP2/.JPC). Todays version of jasper (1.6) do not support all features folly in the full specification of JPEG 2000.
You need to have the free available program "jasper" installed at your search path to make it working. You can find it here:

Do you have any updated guide on how to install JasPer? It seems quite difficult. Microsoft Visual Studio is required, but JasPer tutorial does not give complete information on how to install the software.

It is not clear how to use this code. It has been written that we have to install jasper, but how to link it with mail file is not mentioned.

Would you mind providing some examples to use this code? Plz send some to my email Ty very much

Great work.
Only a small suggestion. For use in windows XP
the "2>/dev/null" in sprintf in both jp2write and jp2read cause errors but if you remove them everything works fine

Hello Peter! There is a problem when running the command "jp2read" in a Matlab console : the filename must be specified (done easily) but what's the meaning of the second parameter of the function??You indicate in the comments that the filename only is necessary. But it appears that the variable "varargin" is mandatory for the rest of the process. Can you help me?
Moreover, what do you mean by "You need to have the free available program "jasper" installed at your search path" ??
